Horvath Practice Problems 95 - 3 Multiply the Boltzmann...

Entropy : Proportional to the number of con f gurations through the Boltzmann equation S = k ln W, (22.1) where k =1 . 38 × 10 − 23 J/K is the Boltzmann constant . ∗∗∗ WorkSheet on Microstate and Con f guration ∗∗∗ Group Work 1. How many di f erent ways are there to permute the let-ters in “CAT”? Call each permutation a microstate then collect equivalent microstates into con f gurations. How does the number of microstates compare to the number of con f gurations? 2. Repeat the about for “ANN”
